The former Spice Girl previously signed a record deal with Sony Australia to try and relaunch her solo music career while serving as a judge on the show.

'Half Of Me', which Halliwell first unveiled during Australia's Footy Show last month, was written with DNA Songs, whose credits include Jessica Mauboy, Timomatic and X Factor Australia Dami Im's winner's single 'I'm Alive'.

By comparison, Im's single - also released this week - sold 44,025 copies to claim the top spot on the charts. A UK release date for Halliwell's track is yet to be confirmed.
